Mitochondrial damage following ischemia. Representative transmission electron photomicrographs from left ventricular tissue from Control (non-ischemic) and Ischemia (30Â min ischemia) hearts. In Control hearts sarcomere structure is preserved and mitochondria have electron dense intracristae matrix and normal size. In Ischemia hearts there is separation myofilaments and severely swollen and electron transparent mitochondria containing numerous mitochondrial calcium granules. Calcium granules (Ca 2+), mitochondrion (M), sarcomere (S) and nucleus (N) are indicated. Scale bars (2Â um are shown)
